Source: Colorado Public Parcels (Colorado Governor's Office of Information Technology) (geodata.colorado.gov), each county assessor's own parcel data, compiled into one statewide layer. Jefferson County’s roll in this data carries little or no year built (under a quarter of its records), so that filter counts almost nothing here. Single family is a parcel whose county land-use description, or Colorado's subclass code (1112 or 1212), says single family (townhomes too); one that only says Residential isn't counted. Colorado’s data here carries no homestead flag, so nothing here says whether the owner lives in the property.
